If it's a teacher, then I don't mind since at least they are willing to repeat the info (assuming there is nor after that). What bothers me the most is when I didn't hear the information and the teacher says "I already answered that" and moves on. At least repeat it ONE more time lol
Ditto to context. It can either be said to point out the other person feels you missed their point or weren't listening, or to let you know that you may not have bee present in the conversation when that angle of it was covered. It can also be used to be annoyingly dismissive of someone's concerns when they are trying to point out a problem they see with something you'd said. In any case its an indicator of a miscommunication between two people because of missed information on either or both peoples' accounts. So it depends so much on who its said to, how its said, what is being talked about, who is part of the conversation, what level of formality the conversation is, etc. On the internet the phrase is typically experienced as rude. Assumptions happen quickly, there's less hesitation to initiate anything than face-to-face, tone is extremely tricky with how many dialects of internet speak exist in english alone.
For me it depends on the context and connotation. If they're saying it to talk down to me like I wasn't getting what they were saying or they're getting annoyed, it's annoying but nothing terrible. Sometimes i'll find it rude but for the most part anytime someone has said it to me, it's in jest cause i was poking fun at them.
They seem fine to me? english isnt my main language, and when someone says those, I think its because they are repeating something that I misses ie, if I came in late to a class or something. Or it helps them rephrase, when i dont understand thing, meaning they said the same thing but with different words, so i think they are fine, should I think otherwise?
if someone is saying that, it usually means i have been blatantly ignoring a point in a discussion, so fair enough. i know I'm guilty of saying this, its good when debating cause if you link your arguments together (you have to give linking evidence too) it makes it a stronger argument.
ive said this to people and it has been taken as rude. But i have a personal pet peeve of hating to repeat things, so.. the only time i "bark" at people with stuff like that phrase is when im reeeally getting tired of saying the same thing over and over- if ive obviously already told specific person. Though, it also depends on how sensitive someone is as well. Some people can be hurt by very small remarks that they just take to a dark place and think the worst of. 3:
I'd say it depends on the context of the conversation. There are different connotations one can put on those phrases, some condescending and asshole-ish, others just standard conversing when talking about a specific topic.
